The invention provides a battery assembly, an electric vehicle, a battery swap station and a charging method. The battery assembly includes: a structural frame; the power battery packs, the battery replacing connector, the battery replacing controller, the alternating current charging base, the direct current charging base, the battery replacing high-voltage cabinet, the battery water cooling unit, the alternating current vehicle-mounted charger and the high-low voltage matching cable are located in the structural frame. Wherein the battery replacement high-voltage cabinet comprises a BMS controller; the high-low voltage matching cable comprises a first voltage cable and a second voltage cable, and the signal voltage transmitted by the first voltage cable is higher than the signal voltage transmitted by the second voltage cable; the battery replacement controller is electrically connected to the BMS controller through the battery replacement connector and a high-low voltage matching cable, and the multiple power battery packs, the alternating current charging base, the direct current charging base and the alternating current vehicle-mounted charger are electrically connected to the BMS controller through the high-low voltage matching cable. And the battery water cooling unit is electrically connected to the plurality of power battery packs and the alternating-current vehicle-mounted charger through high-low voltage matching cables respectively.
